Abstract
A method for calcualting the operating characteristics of operated asynchronous motors fed with pulse voltage is presented in the article. Based on this method, a G-shaped equivalent circuit is displayed for each harmonic in which the pressure curve corresponds to the phase of the current. The suggested model takes into consideration the influence of replacing a current on the active resistance of a rotor at higher harmonics, as well as the increase in magnetic losses due to hysteresis and vortical currents.
